Background Information
PINK1 is a mitochondrial serine/threonine-protein kinase that protects cells from stress-induced mitochondrial dysfunction. The precursor of PINK1 (65 kDa) is synthesized in the cytosol and is imported into the outer membrane of mitochondria. PINK1 is further transferred into the inner membrane. The full-length PINK1 can be proteolytically processed into 52-55 kDa and 45-46 kDa forms (PMID: 18221368; 25108683; 18031932). The half-life of the mature form of PINK1 is very short and it was proposed that the proteasome is involved in its degradation (PMID: 23472196). The gene of PINK1 maps to chromosome 1p36.12. Two alternatively spliced variants exist, the shorter isoform (30 kDa) produced by alternative splicing. Mutations in the PINK1 gene cause autosomal recessive early-onset Parkinson's disease.

Reviews
What customers say
Across 8 reviews, this PINK1 antibody is primarily used for Western Blot at 1:500–1:2000 dilution. Most users report clear detection in mouse tissues (brain, kidney) and HEK-293T cells, especially with overnight 4 °C incubation. However, several reviewers note non-specific bands and limited specificity, with one reporting no expected 63 kDa band or cleavage product and no IF signal. Overall, performance is mixed: reliable for WB in some systems but inconsistent in others, with room for improved specificity.
The reviews below have been submitted by verified Proteintech customers who received an incentive for providing their feedback.
Rhiannon (Verified Customer) (09-16-2026) | No band at 63 kDa in CCCP or DMSO treated cells on western blot with TBS-T + 5% BSA. Band at 45 kDa as shown on product images however no reduction in this band upon CCCP treatment and no band showing 55 kDa major cleavage product so very uncertain that bands shown are due to specific PINK1 antibody binding. Antibody also appears to bind 70 kDa and 100 kDa marker (although not a problem). No signal at all with IF using suggested protocol from Proteintech.

MALLIKARJUNA (Verified Customer) (10-17-2025) | GOOD QUALITY AB FOR WB
|
Javier (Verified Customer) (09-09-2025) | Very good for Western Blotting.
|
aidan (Verified Customer) (04-10-2024) | Good results. Would try higher dilution next time (1:500) on precast gel. Used handcast gel overnight incubation at 4 degrees. Blocked 1 hr 5% milk
 |
Nin (Verified Customer) (02-27-2023) | It is okay to probe PINK1 with two bands although there are some weak non-specific bands.
 |
Yahir Alberto (Verified Customer) (11-12-2021) | The antibody works fine with overnight incubation at 4 °C.
 |
Tanusree (Verified Customer) (12-03-2019) | This antibody works good in western blotting analysis using mouse tissues.
|
HONGXUE (Verified Customer) (08-19-2019) | The specific is not good. You can detect many bands using WB.
